Tariff Hike Disrupts Stainless Steel Market

The US stainless steel market experienced a jolt in June. A sudden tariff increase and a mill price surge hit buyers hard.

On June 3, the US government doubled steel and aluminum import tariffs to 50%. This move, excluding only the UK, affected all other countries immediately. As a result, importers scrambled to renegotiate shipments or cancel orders.

Several buyers told the tariff shift rendered imports “virtually impossible.” Bankruptcy filings rose among foreign-owned auto parts makers and distributors operating in the US. Market participants cited extreme financial pressure from tighter trade restrictions.

 

NAS Price Increase Deepens Market Uncertainty

North American Stainless (NAS) shocked buyers on June 13 with steep price increases effective from July 1, 2025.

The price hikes apply to both new and existing orders and cover most stainless flat and long products. For grade 304 cold rolled coils and sheets, base prices rose by $310/tonne. Grade 316 increased by $464/tonne, and grade 430 by $242/tonne.

The mill also raised hot rolled coil and plate prices significantly. For example, grade 304 plate rose by $397/tonne, while grade 316 surged by $551/tonne. These were NAS’s first increases since February 2022.

Meanwhile, rival Outokumpu announced similar hikes shortly after. However, its adjustments were milder, especially for cold rolled 304 and 316 grades.

 

SuperMetalPrice Commentary:

The US stainless steel market faces dual pressure from import tariffs and domestic mill pricing. While short lead times and stable inventories offer some relief, aggressive price hikes from NAS and Outokumpu may not be sustainable in a weak demand environment. If tariffs soften or demand falters, price rollbacks are likely in late Q3 2025.
